DUMBBELL Fild June 21. 195s jjmm @- 'l MMM @if Patented Feb. y19, "19351 UNITED STATES P.9J-r)surA oi-FICEv i 5 My invention relates generallyj to exercising devices, and particularly concerns improved principlesin the design andconstruction, of dumb.- bells' and'clubs. i

5 g One of .the important objects of my invention is to design ,andconstruct a dumb-bell ofwhichl VVeach end Ythereof is comprised of aplurality of plates vor discs which are of various weights; in Votherwords, it is an object to provide a dumbbell of a character whereby itsweight may be increased oriV decreased according to the satisfaction ofthe user.

Another object of my invention is to provide improved means for lockingthe plates or elements forming the Weightstogether, said `locking meansbeing concealed from view.

Another object isl to'provide a novel covering fori-he handle and endsof the dumb-bell.v

A, further object is to arrange and design one of the coverings in amanner whereby it will tend to serve as a lock Washer. i.

A further object is to provide a `structure in which the handle thereofis provided with a novel covering forming a gripping portion, thecovering also being designed tending to serve as a; lock Washer.

A still further object is to provide a device' of which thestructurethereof is substantial and durable.. 1 v C Many other objectsand advantages ofthe vdevice Will appear afterconsidering the descriptonhereinafter set forth in connection with the drawing hereunto annexedWhereinelements comprising the device are designated by certainnumerals.

With reference to the drawing:-

Fig. l is a view disclosing `a dumb-bell in elevation, a part thereofbeing in section for Ythe purpose of illustration; y

Fig. 2 is a section taken `on line 2-2 through one end of the dumb-bellshow n Vin Fig. 1; and Fig. 3 is a section taken on line 3 3 through thehandle shown in Fig. 1. u

With reference to the-drawing and consideringl the principles of designand constructionV yinvolved in the production of the device, numeral 1indicates a handle having ends respectively designated 2 and 3 securedthereto' bynovel locking means. The Vhandle may obviously be constructedof any suitable material and of Ia diameter and length which will beconvenient and adaptable to the hand of the ordinary user. The handleshown, however, is preferably of vmetal and is provided with butt ends4. The handle. is also preferably of tubular` construction, however,

Y it is to be understood that it may be made tubular adjacent theendsjonly.VV It isalso to be understood thatthe handlemay be taperedfrom the centertowards ,the ends; or in other words, slightly roundedadjacent thecentral portion thereof, and may be made so as togbe of aspecific Weight. The. handle, as shown,A isinternally threaded asindicated at 5.. -A suitable Acovering 6 providing a gripping portionApreferably of resilient materialmay surround the j handle, if desired,and may obviously bel-made of Yany suitable material andof any design.'As-shown, the ends of the covering are extended a slight extent beyondthe endsof-the handles as indicatedat 6', and thus the, covering servesas a lock Washer tending to hold the variousparts in firm assembledrelation.

Considering'the'principles of design and construction oftheV ends 2 `and3which are secured tojthef-handle, it will benoted that each end iscomprised-cf a plurality, of. plates or Adiscs of variousweights, 'l inthe present instance, being an.end'weight,.and 8, 9, and A10, otherVweights,

aperture 11 in order that the threaded extension 12. providedfon andjextending from the' end weight 'lmayextend through theweights 8, 9,

*the latter Weights each being provided with an and 10, witlrthe end 13of the extension 12 threadably engaging the threads 5 of the handle inorder to .properly hold al1 of the Weights in Iirrn assembled relation.Obviously, the weights .may be constructed ofany suitable material andmay be circular inv shapeor otherwise and'be of any suitableweight..D'Toillustrate, plates 8 and 9 may each weigh two. pounds andthe plate Y10, one pound, and thus, itis evident that the weight of thedumb-bell may be increased or decreased as desired. i

The novel locking means for holding the plates, forming the weights,together in assembled relation with respect to the handle as abovereferred to, includes a threaded;V extension 12. The threaded extension12 is preferably provided with anenlargement 141which is embedded in aseat l5 provided in` the end plate or weight 7; thus the end plateserves as an operating member, the end 13 of extension 12 of theoperating memberf?, being engageable with the threads 5 of the handle,thusV 'making it -possible to vary the weight ofthe dumb-bell byaddingor decreasing the Weights, The threaded extension 12 may be of anysuitable' construction, however, in the present instance, is in the formof a bolt of which the headthereof is embedded in the end weight 7 in amanner Wherebymanipulation of the member 'Z will correspondingly movethe extension 12. It willbe'noted that thelojcking meansthus disclosedis of a novel character, and is concealed from View. The end weight 7may be of any suitable design, however, is shown with one face convex asindicated at 16.

As above referred to, lone of the objects of my invention is to providea suitable covering for the ends of the dumb-bell, and with this inView, it will be noted that Vthe plates 8 to l0, inclusive, which formthe weights are each encircled at the periphery by a band of resilientmaterial 17, preferably of rubber. I

The end plate operating member 7, as clearly shown, is provided with acovering 18, which'is similar to eachv of the coverings 17, however denviates therefrom, in view of the faetthat itis more or Aless of channelshape in cross-section,

having a Wall or portion suchas, .1.9, engaging the A convex face 16 ofthe end operatingmember '7,Vand' `the wall or portion 20 thereofextending inwardly between the weights '7 and 8. The wall or portion f'evident that the locking means are concealed from view and that thereare noprojections which extend outwardlyl from-the confinesof the ends.Obviously, either of the bands, such as 17, may be provided with aninwardly extending portion Ysimilar to that designated 20 of the band18, in order to more or less tend to bind the adjacent weights withrespectY to each other.

Although the structure above referred to, is embodied in theconstruction of a dumb-bell, it is to be understood that Vthe sameprinciples may be involved inthe construction of a club.

In View of theforegoing description, it-will be evident that I have`provided a dumb-bell involving novel principles of design andconstruction, and that the weight thereof may be varied as de'- sired.It is also apparent that I have provided novelV means Vfor locking thevarious weightsV together; and also a novel covering for the variousweights, including the handle, and that one of the coveringsfprovidemeans tending to serve asa lock washer, and that'the covering forthehandlernot only provides means for exercising Vthehand but maybe of'acharacter also tending to serveasa Y'Letters Patent is:
